SPECIFICATION forming part of Letters Patent No. 737,987, datedSeptember 1, 1903.

Application filed August 23, 1902. Serial No. 120,807. (No model.)

To aZZ whmn it may concern:

Be it known that I, JOSEPH W'ILSON, a citizen of the United States, anda resident of Lathrop, in the county of Clinton and State of Missouri,have invented a new and Improved Boring and Tenoning Machine, of whichthe following is a full,ciear,and exact description.

The invention relates to portable woodworking machinery; and its objectis to provide a newand improved boring and tenoning machine which issimple and durable in construction, very effective in operation, easilyapplied or removed, and arranged to permit of quickly and accuratelyboring fellies and other articles and forming tenons on the ends ofspokes.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A ractical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement as applied for forming atenon on a spoke. Fig. 2 is a plan view of the same. Fig. 3 is a faceview of one end of a framesection. Fig. 4 is a like View of the bracketfor the feed-lever; and Fig. 5 is a transverse section of the clampingdevice for fastening the machine to 2. spoke or other support, thesection being on the line 5 5 of Fig. l.

The improved boring and tenoning machine is mounted on a frame A, madein sections A and A connected with each other by a bolt 0 to allow ofswinging the sections into longitudinal alinement or into an angularposition one relative to the other, according to the use made of themachine, as hereinafter more fully described.

The outer end of the frame-section A is formed with a shoe A adapted toengage one side of the spoke D or other article on which the machine isto be used, and in order to hold the frame in position on the article Iprovide a clamping device consisting, essentially, of a cam-lever E,having a handle E, and having its pivot E mounted'to turn in and slidevertically in guideways A formed or secured on the shoe A Eyebolts Fengage the pivot E and extend loosely through the shoe A and through aclip-plate F, engaging the side of the spoke or other article D oppositethe one engaged by the shoe A as will be readily understood by referenceto Figs. 1 and 5. Nuts F screw on the eyebolts F and abut against theunderside ofthe clip-plate F, and springs F are interposed between theclip-plate F and the shoe A so as to turn the pivot E in an inwarddirection to engage the peripheral surface of the cam-lever E firmlywith the outer face of the shoe A Now by swinging the handle E of thecam-lever E into the position shown in Fig. 1 the shoe A and clip-plateF are firmly pressed in contact with opposite sides of the spoke orarticle D, so as to securely hold the frame-section A in position on thearticle.

When it is desired to release and disconnect the frame from the spoke D,then the operator swings the handle E over to the left, so as to relievethe shoe A and clip-plate F of pressure and to disengage the same fromthe spoke or article D to allow of slipping the frame off the end of thespoke.

In the outer end of the frame-section A is formed a bearing A in whichis mounted to slide an arm G, carrying the boX G,in which is mounted toslide and to turn the spindle I, provided at its outer end with ahandleJ under the control of the operator for turning the spindle I. Ontheinner end of the spindle I is secured by a set-screw K or otherdevice a tool-carrier K, carrying the tool L for cutting the tenon onthe end of the spoke or for drilling a hole in a felly or other article,it being understood that the tool L is shaped corresponding to theintended use thereof. On the tool-carrier K is formed a reduced portionengaged by a shifting collar N, held in the forked end 0 of a feed-lever0, used for moving the spindle I longitudinally to engage the tool Lwith the work or to move it from the same. In the lever O is formed anelongated slot 0 engaged by a pivot P of a bracket P, secured by thebolt 0 to the frame at the joint of the, sections A and A as plainlyshown in the drawings.

The bracket P has its attaching end in the form of a disk P formed witha transverse slot P (see Fig. 4,) through which the shank of the bolt 0passes loosely, and on the said disk P is also formed a lug P adapted toengage one of a series of recesses A, formed in the periphery of a diskA at the inner end of the frame-section A. Now by loosening the bolt Cthe bracket P can be moved transversely, owing to the elongated apertureP to disengage the lug P from a recess A thus allowing of turning thebracket and sections A and A on the bolt 0 to bring the sections into adesired angular position relative one to the other, with the bracket P,however, standing at right angles to the section A When the desiredadjustment has been made, the bracket P is moved back, so as to engagethe lug P with the registering recess A and then the bolt 0 is screwedup to securely fasten the several parts-that is, the frame-sections andbracketin position.

When the several parts are in the position shown in the drawings, thenon the operator turning the handle J a rotary motion is given to thespindle I, tool-carrier K, and tool L, and on the operator imparting aswinging motion to the lever O the spindle I and its parts are fedinwardly, so as to engage the tool L with the article to be workedthatis, as shown in Fig. 1, to form a tenon on the end of the spoke.

When the device is to be used as a boringmachine,the section A of theframe is clamped to a suitable support and the section A and bracket Pare adjusted to an angular position relative to the section A. Thespindle I is then turned and moved in its bearing J, as above described,by the operator manipulating the handle J and lever O correspondingly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A boring and tenoning machine,comprising a frameformed of two jointed sections, one of said sections having a recessnear the end thereof, cutting mechanism mounted on one of said sections,means mounted contignous to the cutting mechanism and adapted to bemoved into engagement with the recessed portion of the frame, wherebythe frame-sections may be held in an adjusted position, and a leverconnected with the aforesaid means and adapted to be actuated to movethe cutting mechanism longitudinally, as set forth.

2. Aboring and tenoning machine,comprising a frame formed of twosections, pivotally connected, whereby an angular adjustment betweensaid sections is attainable, a spindle adj ustably supported by one ofsaid sections, a tool-holder carried by said spindle, a lever for saidtool-holder, and means mounted adjacent to the pivotal connection of theframes, and engaging with said lever for holding the frames in anydesired angular position relative to each other, substantially as setforth.

3. Aboringandtenoningmachine,comprising a frame formed of sectionspivotally connected with each other, a clamping device on one of saidsections to secure the frame to the article to be operated on, or to asuitable support, a spindle journaled in the other section of the frame,and provided with a tool-carrier, a bracket held adjustable on the jointof the frame -sections, and provided with means adapted to be moved intoand out of engagement with said sections for holding and releasing saidsections from relative adjusted positions, a lever fulcrumed on the saidbracket and engaging the said feed-spindle to move the latter in thedirection of its length, the said lever having an elongated slot engagedby a pivot on the bracket.

4. A boring and tenoning machine provided with a frame made in sections,one of said sections having a series of notches or recesses therein, abolt connecting the sections, an adjustable bracket engaged by the saidbolt, and having a lug adapted to engage one of the notches or recessesin the aforesaid recessed frame-section, and a lever fulcrumed on saidbracket, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH WILSON.
